FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 340,092, dated April 20, 1886.

Application filed November 12, 1885. Serial No. 182,565. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER K. CHANCE, a citizen of the United States, residing at Osakis, in the county of Douglas and State of Minnesota, have invented a new and useful Force- Pump, of which the following is a specification.

My invention relates to improvements in doubleacting lifting-pumps; and it consists in combining with a pump-casing adapted for two verticallyreciprocating valved pumpbuekets certain devices, whereby said buckets can beoperated very advantageously, as will be fully understood from the following description, when taken in connection with the annexed drawings, in which Figure l is a side elevation, partly in section, showing my improved pump arranged inawell. Fig. 2 isa cross-section, enlarged, of the pump-casing, showing a bucket and its lower chain connections, piston rods, and cross-head.

In the annexed drawings, A designates a section of a well; A, the platform at the top thereof, and A the base-stool of the pumpcusing, the feet of which are anchored into the well-curbing, as shown in Fig. 1.

B designates the pump-casing, which consists of two vertical cylinders open at the bottom, and provided at their upper ends with valves a a, which open into a dome, I), from which the discharge-pipe b rises to the top of thewell. Thepump-casingBismounted upon and suitably secured to the stool A 0 O designate two tubular pump buckets, provided with valves 0 c, which open-upward, and also with bails d d, which are connected by a chain, (1, that passes under a pulley, D,

journaled in the stool A. To each one of the buckets are applied piston-rods e 6, connected at their upper ends by a cross-head, e, which heads are connected by chains f f directly to the grooved peripheries of two oscillating pulleys, E E, suitably mounted upon the platform at the top of the well. The pulleys E E are of equal diameter, and are arranged in the same horizontal and vertical planes, so that the chains ff are always coincident with the vertical axes of the pump-cylinders and buckets therein.

G designates a standard mounted upon the platform A, and affording a fulcrum, g, fora long hand-lever, H. The lower end of this lever H is pivoted at h to the inner ends of two links, J J, the outer ends of which are pivoted to arms or levers K K, that are fastened to the journals of the oscillating pulleys E E.

It will be seen from the above description that by vibrating the hand lever H recipro- 6o eating motions are imparted to the pumpbuckets, and that as one bucket ascends the other bucket descends, thus giving a continuous flow of water through the discharge-pipe.

I am aware that it is old in compound or curbing and bearing a pulley, the valved buckets in said casing, the chain connecting said buckets and passed under said pulley,

,the dome at the top of the casing, having a discharge pipe, the valves opening into the dome, the bucket or piston rods connected by So chains to oscillating pulleys, and the compound system of levers, as described, for actuating the buckets.

2. The combination, with the pump-casing,

its buckets, the connecting-chain, the pisto'nrods, and pulley, of the chains ff, connected to the peripheries of oscillating pulleys, the hand-lever, the links J J, pivoted to this lever, and the levers K K, connected to the journals of said oscillating pulleys, all adapted to go operate substantially as described.

3. The combination, with a double-acting pump, as described, andits chain connections, of two oscillating pulleys, E E, of equal diameter, and having their sides in the same vertical plane and their axis in the same horizontal plane, the levers K K on the journals of these pulleys, the vibrating hand-lever, and

the link-connections of this lever with the said levers K K, substantially as described.
